Changelog for Superfish - a jQuery menu plugin
v1.2.1: altered 2nd July 07. added hide() before animate to make work for jQuery 1.1.3.
v1.2.2: altered 2nd August 07. changed over function .find('ul') to .find('>ul') for smoother animations
Also deleted the iframe removal lines - not necessary it turns out
v1.2.3: altered jquery 1.1.3.1 broke keyboard access - had to change quite a few things and set display:none on the
.superfish rule in CSS instead of top:-999em
v1.3: Pretty much a complete overhaul to make all original features work in 1.1.3.1 and above.
.superfish rule reverted back to top:-999em (which is better).
v1.3.1: altered 'li[ul]' to $('li:has(ul)') to work with jQuery 1.2
v1.3.2: added onshow callback option as requested - 'this' keyword refers to revealed ul.
fixed bug whereby multiple menus on a page shared options. Now each menu can have separate options.
fixed IE6 and IE7 bug whereby under certain circumstances => 3rd tier menus appear instantly with text missing when revisited
v1.3.3: altered event attachment selectors for performance increase on menu setup.
v1.3.4: fixed pathClass bug as current path was not being restored. Still doesn't if using keyboard nav (will work on that).
v1.4: store options objects in array $.superfish.o. Also provide public access to $.superfish.defaults
provided backward compat for jQuery versions less than 1.2 via oldJquery option - will use li[ul] or li:has(ul) as needed
added more callbacks, also added option to disable hoverIntent usage if that plugin is detected
v1.4.1: fixed current path not being restored when using keyboard to tab away from the menu completely
optimised code further - now less code
removed addself() in favour of backward compatible add(this)
also remove new mouseenter/mouseleave events on window.unload (due to paranoia)
v1.4.2: 3rd July 2008. added semi-colon at start of superfish.js file to avert script concatenation errors
added pathLevels option to limit the depth of submenus that get restored by pathClass
CSS of main example hugely simplified - other example CSS files less-so.
- top level menu items are not fixed width
- only need to set submenu widths in one place.
- various other improvements.
- class names used in all CSS files are changed to be less generic
released optional Supersubs plugin which dynamically adjusts submenu widths
attach everything to jQuery.fn.superfish to clean up jQuery namespace
removed the multi-tier-all-horizontal-example as it was never a great idea and doesn't seem to be in use
Update documentation text and remove certain caveats which were there to support users of much older versions of Superfish
Documentation now show how to apply bgIgrame 2.1 - it's much easier than before
Add all links and their focus and blur events to the onunload unbind - paranoid about memory leaks
v1.4.3 5th July 2008. documentation completely redone using Mike Alsup's templates.
CSS revised so that all types of menu use superfish.css as a base. Include additional CSS files to acheive alternate styles.
class="sf-menu sf-vertical" creates vertical menu, class="sf-menu sf-navbar" creates nav-bar style menu
v1.4.4 7th July 2008. arrows feature added. If option 'autoArrows' is true, auto-appends (spans) to anchors that have a ul submenu sibling,
and adds class 'sf-with-ul' to anchor.
CSS added to style new arrows, including an 8-bit alpha (NOT INDEXED!) transparent png of arrow - degrades to solid for IE6.
Manually add arrow mark-up to docs and disable autoArrows (via defaults option) to maintain decent performance (for docs page)
Update docs, including zip download, to suit.
Fix CSS bug that had the third tier of the navbar-style menu visible when JS not available.
v1.4.5 9 July 2008. decreased code weight
added drop shadows for capable browsers - added css and 8-bit alpha transparent png image for shadow
remove support for jQuery v<1.2
remove unload clean-up which was there to solve garbage collection problems in early jQuery versions
remove toggling 'visibility' on hide and show which as a fix for an IE bug that is no longer exhibited
removed need for getOpts, rewrote getMenu
use [].join('') instead of string concatenation for performance increase - probably very slight in this case
change selector in 'over' function from '.'+o.hoverClass to 'li.'+o.hoverClass
v1.4.6 added workaround for IE7 shadows. If animation alters opacity then shadow is hidden during the animation and appears after.
This required some JS and a line of CSS, so created shortcut references to lighten code further.
v1.4.7 added back in the visibility toggle that was removed in 1.4.5 as the bug is indeed still exhibited by IE6 & 7
tweaked the look of the shadow slightly and use nicer 32bit png as I now find they behave the same as 8bit png with regard to fades in IE7
v1.4.8 fix over-sight: using 32bit png meant that the shadow image did show in IE6. Rather than go back to 8bit, add code to exclude IE6 from getting shadow class.
use new folder structure recommended by Matt from TopicTrack, for easier updates.
v1.4.9 2009ish. add new onIdle callback for when 'current' path is restored
v1.5.0 Jan 2013. Compatibility fixes for jQuery 1.9. Still backward compatibile. Removed code related to using an image for submenu shadows - just use CSS box-shadow instead (old IE will survive without shadows...unfortunately). Other minor aesthetic code alts.
v1.5.1 31 Jan 2013. Use event delegation for events. Update to patched version of hoverIntent which supports event delegation ( forked for prosperity here: https://github.com/joeldbirch/onHoverIntent - original patch author: Kevin Fernandes https://github.com/KevinFernandes/onHoverIntent ).
v1.5.2 4 Feb 2013. New feature: option to require click to open/close submenus. New feature: Animations on closing submenus. New feature: Add partial support for Android (certain browsers). Full support will be in upcoming version. Minor code clean up.
v1.5.3 14 Feb 2013. Bug fix. IE was throwing errors.
v1.5.4 17 Feb 2013. New feature: Links with submenus only followable when their submenu is open, allows support to be extended to ALL browsers on ALL touch devices. Fixes IE bug with 'useClick' feature.
v1.5.5 20 Feb 2013. Moved flag that temporarily prevents link-follows to touchstart so link clicks via mouse are not delayed. This restores usual submenu behaviour with mouse interaction while retaining full touch device support.
v1.5.6 20 Feb 2013. Bug fix for removing link-clickable delay with mouse interaction.
v1.5.7 20 Feb 2013. Bug fix for previous bug fix.
